I wanted to chastise you for not searching the board, but then it took me a while to find this thread via google even though i knew it existed, and i had to resort to uncommon key words like "central jersey" which you wouldn't guess. Maybe i should reconsider my judgmental ways...
Anyway, the few gyms mentioned in this thread:

are a little far, but close enough (~30 min) as a backup if you don't find anything closer. See e.g.
